This is not correct.  isfinite and fpclassify are both macros on
HP-UX 11.  However, they are broken because they only support float
and double, and not long double.  The function implementations are
_Isfinitef, _Isfinite, _Fpclassifyf and _Fpclassify.  There's also
_Fpclassifyfd where the float argument is cast to double in math.h.

On HP-UX 10, there is no isfinite macro or function.  There are
functions finite and finitef.  Likewise, there are fpclassify and
fpclassifyf functions.  As with HP-UX 11, there is no long double
support.
